User guides for Amazon's Kindle devices cover how to set up online functionality. As of 2015, the user guides for each individual model can be updated by downloading the appropriate .AZW file through a desktop PC and uploading it to the selected Kindle device through a USB cable.
In first generation Kindle Fire tablets, Wi-FI settings can be accessed by tapping the Quick Settings icon located on the Status bar. Wi-Fi can be toggled on or off, and available networks can also be managed through this setting. In some cases, a password may be needed to access the wireless network. Later generations have a similar procedure.
The Kindle device connects to the last used network in the event that more than one network is available. Some models are capable of utilizing 3G and 4G connectivity in addition to the standard Wi-Fi.
